Lance Dutson, one of the bloggers covering the trial for media bloggers association, has written a magnificent piece on the Russert/Mitchell aspect of the Libby Trial. I urge you to read it all. Here are his conclusions:
The contradictory logic evidenced in Russert's testimony is, somewhat ironically, the keystone of the media's case against Libby. The criticisms that his memory lapses are selective could easily be levied against both Russert and Mitchell as well. The media has attempted to convict Libby in the minds of its audience by detailing the absurdity of someone forgetting such obviously important facts and conversations. Yet the very people who have beat this drum for months are now exposed as either equally forgetful, or equally deceitful. The glaring omission of these parts of the testimony from NBC's coverage of the trial makes deceit the increasingly more plausible of the two.
While the media has appeared to have a limitless appetite for the facts and timeframes of what Libby and company were doing about Joe Wilson, the finer points of the defrocking of the High Priest of Washington journalism seems to have encountered an uneasy stomach. This could be because of the discomfort that comes from watching one of your own discredited in public, but more likely it is due to the revelation of the hypocrisy of a media that calls for the head of a politician that plays the same games that they do.
